Keef,
I use Netscape 4.79 for email. Since it is so old, very few viruses are written to target it. For Browsing I use IE6 SP1 (with all the latest patches) and my Security and Privacy Settings Cranked up.
I have not had any problems with it or any comps I have sold. The settings I use will not accept Cookies, ActiveX, Java, or Certificates unless I allow it.
Take Care,
